Linked server problem? No, connectivity issue.

In my new role as a Database Hardener, I also function as Level 2 Production Support.
 

If the Production Support Team can't resolve an issue, they pass it to me.
 

Recently, I was given the task to troubleshoot a linked server issue that had stumped other DBAs.

Both instances were SQL Server 2005. The DBAs tried multiple configurations but the linked server kept failing with either a timeout error or a network interface error.

I started from the beginning and tried to defined the linked server myself.  Same results.

The one thing I think I did different is that I clicked on the For Help: link at the bottom of the error dialog.

http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&ProdVer=09.00.3073&EvtSrc=MSSQLServer&EvtID=11001&LinkId=20476

After reading this entry, I took the recommended user action and pinged the target server via xp_cmdshell from the Query window on the originating server.   No response.


Tada! It was a network connectivity issue and had nothing to do with how the DBA was configuring the linked server.  I advised the DBA to call in a ticket for the network team.


The lesson here is try not to let your focus get too narrow when troubleshooting and use all the help that is offered.

Modifying Endpoint URLs on Availability Group Replicas

I recently had to modify the Endpoint URLs on our SQL Server Availability Group replicas. 

The reason for this blog post is that I could not answer the following questions:

Do I need to suspend data movement prior to making this change? 

Would this change require a restart of the database instance?

I spent enough time searching on my own to no avail that I tossed the question to the #sqlhelp hashtag on Twitter and Slack but didn't get an answer prior to executing the change request.

After reading the relevant documentation, I think it's probably a good idea to suspend data movement for this change.

The T-SQL is straightforward. 

USE MASTER
GO

ALTER AVAILABILITY GROUP [AG1] 
MODIFY REPLICA ON 'SQL2012-1' WITH (ENDPOINT_URL = 'TCP://10.10.10.1:5022');

ALTER AVAILABILITY GROUP [AG1] 
MODIFY REPLICA ON 'SQL2012-2' WITH (ENDPOINT_URL = 'TCP://10.10.10.2:5022');

ALTER AVAILABILITY GROUP [AG2] 
MODIFY REPLICA ON 'SQL2012-1' WITH (ENDPOINT_URL = 'TCP://10…

PowerShell: Quick SQL Server Version Check

I have to keep track of our SQL Server version inventory.  The goal is to reduce the SQL Server 2000 population as fast as possible.


The following PowerShell script will produce a csv file containing the database server name and the version of SQL Server it's running.

AzureRM Templates 101

I've recently started working with AzureRM templates to build new environments.

This document really helped me understand the template structure when I first started looking at them.
https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-authoring-templates

I love examples when I'm trying to learn something new and the Quick Start templates are the mother lode.

Our goal is to incorporate our templates into an Azure Blueprint so that we can quickly build new environments when needed. AzureRM templates can be artifacts of a blueprint.
